FILTER-PRESS.

SPECIFICATION forming part of Letters Patent No. 274,406, dated March 20, 1883.

Application filed September 11,1882. (No modeLl Patented in England Marclr7,1882, No. 1,095. I

T 0 all whom it may concern:

Be it known that I, WILLIAM Gnoacn STRYPE, a subject of the Queen of Great Britwhen formed with central or cross grooves or channels and outlet-holes for thedischarge of the filtered liquid, as heretofore. According to my said invention, I continue the grooves or channels above referred to throughthe bottom or other sides of the filter-plates, which, with the filter-cloth, form the joint between the said plates, instead of terminating the grooves or channels in cross-grooves as now commonly employed. The filtered liquid is thus caused to be delivered direct to the exterior of the press, either'at the bottom or other sides, as may be wished, and may be received into any suitable trough or receptacle common to the whole of the plates, provision being made for intercepting the liquid coming from any particular plate or plates, when necessary, either by the interposition of a subsidiary trough or otherwise.

This invention is applicable to filter-presses constructed wholly of cast-iron, wood, or other material ordinarily employed, as well as to filter-presses constructed partly of a metalsuch, for example, as cast-iron-and lined or covered with another metalsnch, for example, as lead-which is less susceptible to the action of acids. A

In order that my saidinvention may be fully understood, I shall now proceed more particularly to describe the same, and for that purpose shall refer to the several figures on the annexed sheets of drawings, the same letters of reference indicating corresponding parts in all the figures.

Figure 1, Sheet I,.of the accompanying drawings represents a side elevation, and Fig. 2 a transversesection,respectivelypfmyimproved filter-press plates constructed according to my said invention. Figs. 3 and 4 are exactly similar views of a modified construction of such improved form of filter-press plates.

A are the filter-plates, provided with lugs or pieces a, serving to support or carry the said plates in parallel vertical planes upon the framings B.

0 are the usual central apertures or holes in the same, for allowing the passage of the liquid or semi-liquid matter desired to be filtered from one set of plates to the next in the series, or the means of feeding the apparatus throughout its length. Each filter-plate has formed on each side or face a suitable number of shallow straight parallel radial or the like directed grooves or channels, D,which are coir tinned through the bottom edges or lower peripheries, or to other desired points of the same, as shown at E in the drawings. Any convenient number of these filter-plates may be placed together in vertical parallel planes, havingannularor suitably formed filter-cloth joints 0 arranged between each of them, and the whole apparatus thus built up may be held together by bolts, tie-rods, or other convenient known means. The liquid or semiliquid matter to be subjected to the process-of filtration is then forced, under suitable pressme, through the central holes or apertures,

0, provided in the said plates, thus effecting a convenient passage from one set or series of the same to the next, and so on to the end of the apparatus similarly formed or constructed throughout. Asthe matter to be filteredisforced into and partially through such apparatus the more liquid portions of the same are caused to ooze or squeeze through the filter-cloth joints 6, and thence direct out to the exterior of the filterpress through the shallow grooves or channels D, continued or extended without interruption to the bottom sides or peripheries or other equivalent convenient positions, E, of the said plates A. The separated liquids etiected by direct egress between the various plates, as aforesaid, may be received or collected in any convenient trough or receptacle, or any number of such receptacles provided-for such purpose. In this manner it will be understood that'an eli'ectual and ample egress for the that, notwithstanding any undue fluctuations liquid matters to be separated is obtained so of pressure throughout the apparatus to which the matters to be filtered are subjected, sufficient means of direct relief without the use ner, the amount of which will vary according to the pressure applied and the arrangement of the filter-press.

According to the modified construction ofv filter-plates shown at Figs. 3 and 4, Sheet II of the drawings,the aforesaid shallow grooves or channels D are formed in a radial direction, and also connected with or intersected by similar auxiliary shallow grooves or channels, d, having concentric direction or relation. It will be understood that other similar convenient means of surface intercommunication may be employed to facilitate therprocess of filtration.

In Fig. 4 the filter-plate joints 0 are Likewise shown of modified construction that is, in lieu of being formed by the intervention of separate rings or annular pieces, as at c, Fig. 2, the peripheral edges of the same are formed with raised portions, so as to present the required connecting-surfaces. In other respects corresponding letters indicate similar parts to those described with reference to Figs. 1 and 2 of the drawings. Although the said plates have been described as being preferably arranged and used in vertical planes, it will be obvious that, if desired, they could be employed in horizontal or angular planes; and it may be also observed that square or other convenien tly-shaped plates might be employed instead of the round plates described; and also the feeding of the apparatus could be effected at the sides or other portion of the surface of the filter-plates in lieu of the center, as herein set forth.

The above-described apparatus for filtration purposes may be constructed of iron, wood, or any other suitable materials or combinations of the same commonly employed.

I claim as my invention A filter-press consisting of a number of filterplates arranged side by side, the said plates having on their faces a number of grooves or channels, D, extending to the extreme peripheries of the plates, and so forming a number of separate direct outlets for the liquid to the exterior of the filter, substantially as de- Y scribed. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
